No transfer record matches. APNIC's statistics show it reserved on 2026-10-28 and allocated (dated 2026-10-27) on 2026-10-29. The tracker saw this range removed from registration on 2025-10-27 (AS146960), so it appears to have been issued again from APNIC's pool.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-10-27. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2021-08-24) on 2025-10-27 and available on 2025-10-28. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, but its statistics have released returned ASNs a year after the removal or later since 2014, so the tracker estimates the hold ends on 2026-10-27. That is what APNIC has done, not a rule it states. This does not confirm availability.

No transfer record matches. APNIC's statistics show it available on 2021-08-24 and allocated (dated 2021-08-24) on 2021-08-25. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.
